update ge/he/syssq algos to make them more generic and get the possibility to accumulate squares over columns or rows

    improve user's doc style
    add some explanation about the code structure in the main doxygen
    fix coverage in analysis sonarqube
    add a release job to automatize release publication
    change the cdash server to my.cdash.org which is more recent and reactive than cdash.inria.fr
    fix the version number, dates and authors in headers to prepare the release 0.9.2

change the way we include our own header files --> relative to the root - when plasma is in the same env, chameleon can take some headers not belonging to it (ex: #include descriptor.h, this file states in plasma install dir also) which make compilation errors

change copyright - correct whitespace - place cmake module depending on chameleon in cmake_modules and no more in cmake_modules/morse
